ProductNameFormat
Classdesc
ProductNameFormat provides methods to format a string with product name substitution. An argument pattern "$(pn)" is used as the placeholder for the product name in a format string resource.
Multiple product name types are available to use with format methods. Below is an example of Amazon Echo Show 5 product names in different types, | Type | Name | | :———– | :———————————- | | Generic | Device | | Short | Echo Show 5 | | Medium | Echo Show 5 (3rd Gen) | | Long | Echo Show 5 (3rd Generation) | | Full | Amazon Echo Show 5 (3rd Gen) | | Generational | Amazon Echo Show 5 (3rd Gen) |
A Default type is also available and maps to Medium type.
Example
import { ProductNameFormat, ProductNameType } from '@amazon-devices/keplerscript-kepleri18n-lib';
...
// Pattern should be retrieved from string resources. It's hardcoded here for brevity of example only.
const pattern: string = "This $(pn) is wifi enabled.";
const message: string | null = ProductNameFormat.format(pattern, ProductNameType.MEDIUM);
if (message === null) {
// Error
return;
}
// For the above Amazon Echo Show 5 product names example, message is "This Echo Show 5 (3rd Gen) is wifi enabled."

Methods
format()
staticformat(pattern,productNameType,args?):null|string
Formats given pattern with product name substitution for the default locale. Optionally, the pattern may also be a MessageFormatClassic pattern with named arguments. The pattern is expected to contain one or more "$(pn)" substrings as placeholders for the product name.
In addition, this method supports "pngender" for product name gender message selection. To use it, just specify "pngender" in place of the IMessageFormatClassic select-format argument, and write select-format clauses based on the possible genders of other, feminine, masculine, neuter, female, male. For example,
Parameters
pattern
string
The pattern to format.
productNameType
ProductNameType = ProductNameType.DEFAULT
Type of product name to use.
args?
Map<string, string | number | Date>
Optional map of argument names to their values.
Returns
null | string
Formatted message with the specified product name replaced in place of "$(pn)" on success, null on failure.
Example
{pngender, select,
* feminine {$(pn) displays a notification on her screen.}
* masculine {$(pn) displays a notification on his screen.}
* other {$(pn) displays a notification on its screen.}}
If the current product gender is feminine and the product name is "Echo Show", this method will return
"Echo Show displays a notification on her screen."
Note
- Do not use the name "pngender" as a named argument, as it is a reserved key by ProductNameFormat. If a "pngender" named argument is passed in the argument map, this method will fail.

staticformatPositional(pattern,productNameType, …args):null|string
Formats given pattern with product name substitution for the default locale. Optionally, the pattern may also be a MessageFormatClassic pattern with numbered arguments. The pattern is expected to contain one or more "$(pn)" substrings as placeholders for the product name.
